Question : Referential Integrity and Constraint Question
Hi,
I have two tables, "Customer" and "Inactive"
Customer Table
cust_id (PK) cust_name status
1 ABC Company 0
4 XYG Company 2
Status Table
status(PK) status_desc
0 some desc
1 diff desc
2 2nd desc
I want to create a constraint between the PK of the Status table and the Status column in the Customer table. What would be the SQL needed to do this?
I basically want to prevent a user from creating a record in the Customer Table with a value in the status column that doesn't exist in the Status table.
Hope that makes sense.
